FINDER.

Patented Nov. 5, 1918.

Original application filed February 17, 1905, Serial No. 246,169.Divided and this application filed December 12, 1916, Serial No.136,428. Renewed August 31,

To all whom it may concern:

Be it known that I, JOSEPH BECKER, a citizen of the United States,residing at Washington, in the District of Columbia, haveinvented .a newand useful Improvement in Finders, of which the following is aspecification.

The present application, identified for convenience of reference as CaseAr, is

Division four of my prior application Case Q, Serial No. 2%,169, filedFebruary 17, 1905, now Patent 1,210,136, issued Dec. 26, 1916; and itrelates to certain features of said Case J which are separatelypatentable under the head of finders.

My present invention consists in a simple, inexpensive, and veryconvenient modified form of the adjustable finder shown in Fig ures 10and 11 of my Case Aq or Division three of J, filed December 11, 1916Serial N 0. 136,298.

The accompanying drawing shows it in vertical section.

On referring to the said Figs. 10 and 11 of my said Case Aq,'it' will beseen that vertical adjustment of the line of sight is obtained in thatstructure by a horizontal adjustment of the rear sight.

In the present'structure the same verticaladjustment of the line ofsight is secured by Vertical adjustment of the rear sight.

The camera box 320,.partition 321, plate 323, floor 324, wall 325, lens327, andkeeper 328 are, respectively, identical with the 1918. SerialNo. 252,262.

similarly numbered parts of Figs. 10 and 11. But the rear sight here isa simple pin or screw 310 driven into the flooring 32% of the sightingrecess and adapted to act on the central finder 350, instead of on thelowest rays 304:. Lateral adjustment is pro vided for by starting thepin or screw in the proper lateral position; and then, by driving thepin or screw more or less its head can be accurately brought into thepath of the central finder ray 350, as seen in the figure. Thisconstitutes a very simple, accurate and convenient form of finder.

The pyramid of rays from the finder lens 327 to the eye at E isindicated here, as in my said Case Aq, by a heavily marked arc alpha(0:).

What I claim as my invention and desire to secure by Letters Patent is:

The combination with a camera and an eccentric divergent lens mountedthereon, as a finder, of a sight mounted adjustably on the camerabetween the said lens and the position to be occupied by the operatorseye; said si ht consisting in a diminutive post adapted to be driven atany desirable point of, and to any desirable depth into, a partthatremains stationary with relation to the said finder. lens while the sameis in use.

In testimony whereof I have signed my name to this specification.

' JOSEPH BECKER.
